Christine Brown (Alison Lohman) is a loan officer with a good job and a promising future. With a promotion up in the air between her and another employee, her boss, Mr. Jacks (David Paymer), advises her that she needs to demonstrate she can make "the hard calls" and make tough decisions. When Mrs. Ganush (Lorna Raver), an elderly Slavic woman, asks for a third extension on her mortgage, Christine, against her better instincts, denies her in an attempt to prove herself. In desperation, Ganush prostrates herself before Christine, begging and kissing the hem of her skirt. As a crowd of customers and employees gathers, Christine panics and shoves the woman away, gravely insulting her.

That night, in a parking garage, Ganush, enraged and humiliated, exacts revenge by pulling Christine out of her car, and rips one of the buttons on her jacket off before using it to place a curse upon her. Shaken by this confrontation, but sure that no further harm will come of it, Christine tries to forget what has happened and move on with her life- that is until she is haunted around the clock by a mysterious and terrifying entity that only she can see. She confides in her boyfriend, Clay Dalton (Justin Long), however, he is too skeptical to believe her stories about terrifying demons that are constantly terrorizing her.

Christine keeps having frightening encounters with a deformed Ganush, who is making her life a living hell. As her relationship starts to fall apart and her job starts to crumble, Christine becomes increasingly scared. Mr. Jacks starts to think that she may be suffering from psychiatric troubles and starts to confront her himself. With nobody to believe her, Christine makes a last desperate attempt to prove her sanity by consulting a psychic, Rham Jas (Dileep Rao), who tells her that she has been cursed and that she is to be tortured for three days by a demon called the Lamia before being dragged to hell to burn for eternity. Horrified by this revelation, Christine begins a race against time to save her soul from damnation, trying various methods to beat the curse. Finally, she is told that the only way to get rid of the curse is to give the item Ganush cursed (the jacket button) to someone else. Christine ends up giving the button, in a sealed envelope, to the corpse of Ganush, who died shortly after cursing Christine.

Relieved that she beat the curse, Christine goes to a train station to meet Clay. He then reveals to her that she grabbed the wrong envelope, and he had the envelope-sealed button on him. Shocked, Christine falls onto the train tracks while a train is coming towards her. Before she gets hit, however, demonic hands pop out of the ground, and all Clay can do is watch in horror as they pull Christine into hell, graphically incinerating her skin in the process.
